Entity Model Features Mod Download for Minecraft 26.3 NeoForge: Custom Mob Models from Packs
Quick answer: Entity Model Features is a free client-side mod that lets Minecraft use custom entity models from resource packs, in the format OptiFine made standard. The latest release is Entity Model Features 3.3.12 for Minecraft 26.3, and the download below is the NeoForge build, verified on Modrinth today. The mod on its own changes nothing visible. Its job is to unlock what resource packs can do, so pair it with a pack that ships custom entity models. It needs NeoForge for Minecraft 26.3, and it works on its own with no other mod required.
Resource packs can retexture anything in Minecraft, but retexturing has a limit. A texture is paint on a fixed shape. A pig is always shaped like a pig, a villager is always shaped like a villager, and no amount of painting changes the silhouette. Pack makers who wanted new shapes needed a way to change the model itself: the geometry, the parts, and how those parts move. OptiFine offered that through its custom entity model format, and a large library of packs was built on it. Players who moved away from OptiFine lost those models, and packs that relied on them fell back to vanilla shapes with new paint.
Entity Model Features, usually shortened to EMF, brings custom entity models back without OptiFine. It comes from developer Traben and has passed 107 million downloads on Modrinth. It reads the same model format OptiFine used, so packs made for OptiFine work with EMF without being rewritten. It is the companion to Entity Texture Features, which handles custom textures for entities. EMF handles shapes and animation. Together they cover most of what OptiFine offered for entities, split across two small mods.

What Entity Model Features actually does
EMF lets a resource pack replace an entity’s model with a custom one, defined in the pack’s files. A pack can give a creeper a different body shape, give a villager a hat that moves with its head, give a wolf a tail that wags in a new way, or replace a mob entirely with a shape the vanilla game never had. The model files use the format OptiFine documented, with parts, pivots, rotations, and animations, so a pack maker who learned that format does not need to learn a new one.
Animation is the part that makes custom models feel alive rather than static. EMF supports the animation system from that same format, which lets pack makers define how parts move: walking cycles, idle sways, attack swings, and special animations tied to what the entity is doing. A custom model that only stands still looks wrong in a game where everything moves, so animation support matters as much as the shape itself. Packs that use it well produce mobs that move in ways vanilla mobs never did, while still fitting the blocky style of the game.
EMF also supports model variants tied to conditions, in the same way its texture companion supports texture variants. A pack can say that a mob uses one model in one situation and another model elsewhere, for example a different shape for a named mob, or a seasonal variant. These rules live in the pack’s files, and EMF reads them at load time. The mod adds no models of its own, so the variety you see depends entirely on the pack you choose.
The important catch: EMF alone changes nothing
Install EMF with no resource pack, and your game looks exactly as it did before. The mod adds no models, no textures, and no new mobs. It only unlocks features for packs that use them. If you install EMF and see no change, that is normal, and it means the mod is working but your pack does not use custom entity models.
To see the difference, install a resource pack that advertises custom entity models, OptiFine model support, or EMF support, then turn the pack on in Options, then Resource Packs. Packs that mention EMF by name are the safest bet, since their makers tested against this mod. A pack that only says it works with OptiFine will usually work too, because EMF reads the same format, but test it in a singleplayer world first and check a few mobs before you rely on it.
Compatibility
| Item | Detail |
|---|---|
| Latest version | 3.3.12 |
| Minecraft version | 26.3 |
| Loader in this download | NeoForge |
| Other loaders | Fabric and Quilt builds exist on Modrinth for the same version |
| Needs anything else? | No. No library mod required |
| Companion mod | Entity Texture Features, for custom entity textures from packs |
| Client, server, or both | Client-side. Works on any server, with no server mod needed |
EMF works on any server because it only changes how your computer draws entities. Other players see their own models, and the server sees nothing different. It works alongside performance mods such as Sodium on NeoForge, and alongside shader mods such as Iris, though shader packs can change how custom models are lit, so check a new pack and shader combination in a test world before you settle on it.
Do not run EMF together with OptiFine itself. Both mods try to handle the same model format, and running both causes duplicate handling and visual errors. Pick one. If you already use OptiFine for its custom models, EMF is the replacement for players who want those models without OptiFine. If you use EMF, leave OptiFine out.
How to install Entity Model Features
- Install the NeoForge loader for Minecraft 26.3 from the official NeoForge site, if you do not have it yet. In your launcher, pick the NeoForge 26.3 profile.
- Download Entity Model Features 3.3.12 using the button above. The file is called entity_model_features-3.3.12-26.3-neoforge.jar and is about 666 KB.
- Open your Minecraft folder. On Windows, press Win + R, type %appdata%\.minecraft and press Enter. On macOS, open Finder, press Cmd + Shift + G, and type ~/Library/Application Support/minecraft.
- Open the mods folder inside it. If there is no mods folder, create one with exactly that name.
- Move the entity_model_features-3.3.12-26.3-neoforge.jar file into the mods folder. Do not unzip it.
- Launch the game with the NeoForge 26.3 profile. The game loads normally, with no setup step.
- To see the effect, add a resource pack that uses custom entity models. Put the pack file in the resourcepacks folder, then turn it on in Options, then Resource Packs, then Done. Load a world and look at the mobs the pack covers.
Troubleshooting
Nothing looks different after install. This is expected if your resource pack does not use custom entity models. Install a pack that advertises EMF or OptiFine model support, and check that the pack is actually enabled. A pack sitting in the resourcepacks folder but not moved to the selected side does nothing.
The game crashes on startup. Check the loader and version match: the file name must contain “neoforge” and “26.3”, and the launcher profile must be NeoForge 26.3. Also check that OptiFine is not in the mods folder at the same time, since the two conflict.
Some mobs look right and others look broken. A pack covers only the mobs its maker modeled. A mob with a half-finished model, missing parts, or a texture that does not match the new shape is a pack problem, not a mod error. Check the pack’s description for which entities it covers, and test the pack with EMF alone before adding other rendering mods.
A custom model animates wrongly, with parts bending in odd directions. This usually means the pack’s animation file expects a different model version or was made for an older format. Try the pack’s latest release, and if the problem stays, report it to the pack maker with the mob name and a screenshot. EMF reads the pack’s files as written, so a bad file produces a bad model.
The game runs slower with a heavy model pack. Custom models with many parts cost more to draw than vanilla models, and a pack that remodels every mob in the game can cost frames on a weak graphics card. If this happens, use a lighter pack, or pair EMF with a performance mod such as Sodium to recover the lost frames.
Is Entity Model Features safe to download?
Yes, when you get it from Modrinth, where the developer publishes it. The file on this page comes straight from Modrinth’s CDN, and the version number and file name match the developer’s release. Avoid repost sites that bundle mods with installers or ask you to run an extra program. A real Minecraft mod is a single .jar file that you drop into the mods folder. Never enter a password or personal detail into any site that claims to offer a mod download.
Frequently asked questions
Does EMF work without a resource pack?
It loads and runs, but it changes nothing visible. Its features only show when a resource pack uses them, so pair it with a pack that advertises custom entity models.
Do I need Entity Texture Features too?
Not always. EMF handles models. Entity Texture Features handles textures. A pack that only changes shapes needs EMF alone. A pack that changes both shapes and textures needs both mods, and most full packs change both, so many players install the pair.
Does EMF work with OptiFine packs?
Yes, in most cases, because EMF reads the same model format OptiFine uses. Test a pack in singleplayer first, since a pack built for a much older OptiFine version may use rules EMF no longer matches.
Is EMF client-side?
Yes. It only changes how your computer draws entities. You can join any server with it installed, and other players are unaffected.
Can EMF add new mobs to the game?
No. It changes the shape and animation of mobs that already exist. Adding a new mob with new behavior needs a content mod, not a resource pack feature.
Which loader build should I pick?
Pick the build that matches your loader and your Minecraft version. This page offers the NeoForge build for 26.3. Fabric and Quilt builds for the same version are on the same Modrinth project page.
Verdict
Entity Model Features is a small mod with a clear job, and it does that job well. It restores a set of pack features that many players missed when they left OptiFine, it reads the same format pack makers already use, and it stays out of the way otherwise. Its only real weakness is that it does nothing on its own, so new users can mistake a working install for a broken one. Pair it with a good pack, add Entity Texture Features if the pack changes textures too, and the new shapes it brings to familiar mobs are hard to give up once you have seen them.
